Whether the valve cleaning, functions are in good condition, and repeatedly turn began to work more than three times, to ensure that the valve before installation is accord with conditions conform to the standard valves. 。 1, before the installation of investigation: first of all, the material of seizing pneumatic welding ball valve, pressure, temperature performance indicators, such as whether to need exactly the same. 2, pneumatic welding ball valve and pipeline petition: first of all, be sure to disassemble the valve, after welding assembly. 3, after installation of seizing: three type pneumatic welding ball valve after the completion of installation, should open/close three times this is normal, and implemented according to the requirements of the standard pressure, pressure can not be greater than the standard one. 2 times, test three times after opening and closing valve, by clearly acknowledged, and the valve is normal. 【 Q 】 Three type pneumatic welding ball valve installation process' A 】 Ball valve installation and performance of fixed number of year of quality to the survival of the valve is shut, three type pneumatic welding ball valve installation and the installation before and after the investigation should be abidioy his basic procedures. If be sure to spot welding position on pipeline, be sure to guarantee to reduce the temperature of hand Marine valve can ensure the temperature of the valve can not more than 120 ℃, and then apart to remove the screw body, cover and pipe welding, cooling down to room temperature, the valve body to ensure tight sealing gasket is among, steel ball the whole paper, petition average locking screw to symmetric, safeguard tightly sealed gasket stress on average, to lock the spring gasket flatten, just joint between the Industrial Valves bonnet.
